Synthesis of cyclic chiral alpha-amino boronates by copper-catalyzed asymmetric dearomative borylation of indoles

A copper(i)-catalyzed dearomative borylation of N-alkoxycarbonyl protected indole-3-carboxylates has been developed. The boron addition in this reaction occurred regioselectively at the 2-position of indoles followed by diastereoselective protonation, affording the corresponding stable cyclic chiral -amino boronates (2-borylindolines) in moderate to good yields with excellent diastereo- and enantioselectivities. The product 2c could be used as a versatile precursor to undergo subsequent stereoselective transformations, delivering highly functionalized 2,3,3-trisubstituted chiral indolines.

Longitudinal relationship of amino acids and indole metabolites with long-term body mass index and cardiometabolic risk markers in young individuals

Amino acid metabolites in biofluids are associated with high body mass index (BMI) and cardiometabolic abnormalities. However, prospective investigations regarding these associations are few, particularly among young individuals. Moreover, little is presently known about the impact of long-term high BMI. Using data from the DOrtmund Nutritional and Anthropometric Longitudinally Designed study (111 males and 107 females), we prospectively investigated relations between repeatedly measured urinary levels of 33 metabolites and (1) previously identified long-term BMI trajectory groups from childhood into late adolescence and (2) cardiometabolic risk markers in late adolescence-young adulthood, in sex-specific linear mixed regression models. Males with long-term overweight had lower indole-3-acetic acid when compared to others. Further, methionine, isoleucine, tryptophan, xanthurenic acid, and indole-3-carboxaldehyde were negatively associated with C-reactive protein (CRP), but 5-hydroxyindole-3-acetic acid was positively associated with CRP. No associations were observed in females. Long-term overweight from childhood into late adolescence is associated with decreased urinary levels of gut bacteria-derived indole-3-acetic acid, and several urinary amino acids, including gut bacteria-derived indole-3-carboxaldehyde are associated with elevated CRP later on in life. Taken together, our data suggest that indole metabolites, and their gut bacteria producers play potentially important roles in overweight-related inflammation.

Yield response of common bean to co-inoculation with Rhizobium and Pseudomonas endophytes and microscopic evidence of different colonised spaces inside the nodule

Microbial inoculants are gaining prominence in technologically advanced agri-systems due to the need for alternatives to the most pollutant agricultural inputs. The objective of this work was to improve the agronomic performance of the rhizobial inoculants for common bean, based on the superior native strain Rlp-LCS0306 of Rhizobium leguminosarum bv. phaseoli (R), through co-inoculation with non-rhizobial partners, namely the autochthonous isolate RVPB2-2 from Pseudomonas brassicacearum subsp. neoaurantiaca (P) and the type strain of Azotobacter chroococcum. It has been reported that co-inoculation improves nodulation, nodule functions and plant growth, although there is a lack of field testing in technologically advanced agri-systems. This work bridges this gap. In the field trial which was carried out in two different environments, the consortium R + P was the most successful, because it increased the N-2 fixation by 51.7 kg ha-1 (87 %) and the yield by 1337 kg ha-1 (59 %), compared with the uninoculated and unfertilised control. In addition, the increased yield observed following inoculation with the above indicated consortium was 16.7 %, compared with the single rhizobia inoculation, and this increase was also superior to that observed with other consortia. The superiority of the R + P consortium could partially be explained because in this study, there was an increased tendency for improved nodule biomass and function following co-inoculation. While this increase was not deemed to be statistically significant, it is noteworthy that nodule biomass increased by 25 % in average and N-fixed by more than 20 %, which, in turn, could be explained by the indole-3-acetic acid (IAA) production and 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity of the P strain. However, further delineation of the system is required in order to explain the yield improvement exerted by the consortium. Here, we observed, i) the strong plant growth-promoting potential displayed by the P strain; ii) the colonisation of the nodules by the P strain; and iii) the strategy of colonisation of complementary spaces inside the nodules by P (intercellular) and the rhizobia (intracellular), by confocal microscopy.

Performance and microbial community analysis of bioaugmented activated sludge for nitrogen-containing organic pollutants removal

Nitrogen-containing organic pollutants (quinoline, pyridine and indole) are widely distributed in coking wastewater, and bioaugmentation with specific microorganisms may enhance the removal of these recalcitrant pollutants. The bioaugmented system (group B) was constructed through inoculation of two aromatics-degrading bacteria, Comamonas sp. Z1 (quinoline degrader) and Acinetobacter sp. JW (indole degrader), into the activated sludge for treatment of quinoline, indole and pyridine, and the non-bioaugmented activated sludge was used as the control (group C). Both groups maintained high efficiencies (> 94%) for removal of nitrogen-containing organic pollutants and chemical oxygen demand (COD) during the long-term operation, and group B was highly effective at the starting period and the operation stage fed with raw wastewater. High-throughput sequencing analysis indicated that nitrogen-containing organic pollutants could shape the microbial community structure, and communities of bioaugmented group B were clearly separated from those of non-bioaugmented group C as observed in non-metric multidimensional scaling (NMDS) plot. Although the inoculants did not remain their dominance in group B, bioaugmentation could induce the formation of effective microbial community, and the indigenous microbes might play the key role in removal of nitrogen-containing organic pollutants, including Dokdonella, Comamonas and Pseudoxanthomonas. Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) analysis suggested that bioaugmentation could facilitate the enrichment of functional genes related to xenobiotics biodegradation and metabolism, probably leading to the improved performance in group B. This study indicated that bioaugmentation could promote the removal of nitrogen-containing organic pollutants, which should be an effective strategy for wastewater treatment.

Synthesis, spectroscopic, computational and drug docking studies of 1-(benzenesulfonyl)-2-methyl-1H-indole-3-carbaldehyde

An N-Substituted 1H-indole derivative having an empirical formula C16H13NO3S was synthesized by the condensation of 2-Methyl-1H-Indole-3-carbaldehyde and benzene sulfonyl chloride in presence of a phase transfer catalyst of type quaternary ammonium salt in basic conditions. Then the compound was characterized by using FT-IR, UV-Visible and NMR spectroscopic methods. Thus the obtained experimental results were effectively compared with DFT studies in arriving the structural characteristics of the title compound. From vibrational analysis, it was observed that carbonyl frequency is somewhat lower than a typical aldehydic stretching frequency and it could be possible only when the formyl group is coplanar with the ring and subsequent resonance conjugation reduces its force constant. Similarly, the optical absorption behavior of a typical indole ring suffered from a bathochromic shift due to the presence of ring substituents. Finally, the molecular drug docking studies of the title compound were performed using AutoDock 4.2 tools to ascertain its binding mode, efficiency and the nature of chemical interactions with the target proteins and it has been predicted theoretically that the binding efficiency of the ligand on the target receptor surface was found to be better in the case of Gram positive bacteria S. Aureus than the Gram negative N. Meningitidis. (C) 2018 Published by Elsevier B.V.
